Physics Based Geometric Design

Geometric modeling has proved to be crucial to computer graphics and computer aided geometric design CAGD During the past several decades numerous geometric formulations have been proposed for a large variety of geometric modeling applications In this paper we survey the diversity of shape representations ranging from the primitive polynomial to the sophisticated Non Uniform Rational B Spline N...

Hoist: A Second-Generation Expert System Based on Qualitative Physics

Hoist system for hypothetical reasoning, Wif models the functionality of all the components, thereby creating a causal model of the Mark 45 lower hoist. This model not only simulates the correct operation of the lower hoist, it also simulates the boundaries of faulty operation. The lower hoist in its actual form (a machine in the real world) is not computer accessible; a computer cannot connect...

Qualitative Physics based on exact physical principles*t

Consider a two-body collision process . Raiman[1986] observed that the conventional qualitative approach to this problem amounts to suppressing the mass information, which becomes inadequate when one wants to determine the direction of the velocity of an abject after a collision . He resolved this by going back to the original algebraic equations, which have all the mass factors . He then proce...
